Intelligent flow-variable spraying controller based on laser detection

Abstract

The invention discloses an intelligent flow-variable spraying controller based on laser detection. The intelligent flow-variable spraying controller based on laser detection comprises a laser sensor, a touch screen, an embedded vehicle-mounted main control unit, a portable wind speed and wind direction tester, a data acquisition unit, a speed sensor, a pressure sensor, a flow sensor, an inclination sensor, a multi-channel variable-flow control unit and a plurality of electromagnetic valves, wherein the electromagnetic valves, the laser sensor, the touch screen, the portable wind speed and wind direction tester, the data acquisition unit and the multi-channel variable-flow control unit are all in communication with the embedded vehicle-mounted main control unit, signals collected by the speed sensor, the pressure sensor, the flow sensor and the inclination sensor are transmitted to the data acquisition unit, and the electromagnetic valves are controlled by the multi-channel variable-flow control unit. According to the intelligent flow-variable spraying controller based on laser detection, the dynamic delay compensation mechanism is adopted, and the influence of factors such as output delay of a control system and the wind speed of a field is avoided. By the adoption of the intelligent flow-variable spraying controller based on laser detection, and the accuracy of agricultural pesticide spraying is improved, environmental pollution is reduced. The intelligent variable spraying controller based on laser detection has important scientific significance and high application value.

Description

technical field [0001] The invention relates to a controller of a multi-channel variable flow vehicle-mounted sprayer, in particular to an intelligent variable spray controller using laser detection. Background technique [0002] my country is a large agricultural country, and agricultural spraying is an effective method to control pests and weeds in nurseries and orchards. However, my country's current plant protection machinery and pesticide application technology are still relatively backward, and manual and knapsack traditional sprayers with low efficiency and high strength are still widely used. Affected by various plant shapes, mixed cultivation, seasonal growth changes, planting spacing and other factors, the spraying effect of traditional sprayers is relatively poor. Under the existing plant protection equipment and pesticide application technology in my country, the effective utilization rate of pesticides is low, the loss is large, and the spraying distribution is...

However, my country's current plant protection machinery and pesticide application technology are still relatively backward, and manual and knapsack traditional sprayers with low efficiency and high strength are still widely used

Affected by various plant shapes, mixed cultivation, seasonal growth changes, planting spacing and other factors, the spraying effect of traditional sprayers is relatively poor

Under the existing plant protection equipment and pesticide application technology in our country, the effective utilization rate of pesticides is low, the amount of loss is large, and the distribution of spraying is uneven, resulting in pesticide residues in agricultural products that are dozens of times higher than those in developed countries.

The low level of agricultural pesticide application technology has caused the waste of pesticides and environmental pollution, which has caused problems such as environmental safety, agricultural product and fruit safety, operator safety and economic benefits.
